Enabling ASNConnect

ASNConnect by BeyondTrust is a third-party remote access solution that allows Stratus Customer Service to remotely connect to various components of a ztC Endurance system for assistance with diagnostics, troubleshooting, and service/support activities.

ASNConnect allows Stratus Customer Service to connect remotely to the following:

  • On BMC A: the SSH interface and the BMC Web console

  • On BMC B: the SSH interface and the BMC Web console

  • On the VMware ESXi host: the ESXi Host Client or vSphere Web Client

  • On the Stratus Management VM: the SSH interface, the file transfer interface, and the ztC Endurance console​

  • On the standby compute module: the SSH interface

To use ASNConnect, you must install software on your ztC Endurance system.

Checking Your Connection to ASNConnect

Before you install ASNConnect on your ztC Endurance system, use the curl command to make sure that your ztC Endurance system can connect to asnconnect.stratus.com over TCP port 443. The following example shows a successful connection.

curl -v asnconnect.stratus.com:443
* About to connect() to asnconnect.stratus.com port 443 (#0)
*   Trying 3.145.54.234...
* Connected to asnconnect.stratus.com (3.145.54.234) port 443 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.29.0
> Host: asnconnect.stratus.com:443
> Accept: */*

* Empty reply from server
* Connection #0 to host asnconnect.stratus.com left intact

Installing ASNConnect on the ztC Endurance System

  1. To start the installation, run the following command from the ztC Endurance Management VM:

    sudo /opt/stratus/sbin/setup_bt install

  2. When the installation completes, run the following command on Standby B:

    sudo /opt/stratus/sbin/setup_bt install

  3. When the installation completes, log in to the ztC Endurance console​. See Logging In to the ztC Endurance Console.

  4. From the ztC Endurance console​, perform a Smart ExchangeClosed A proprietary process that maintains system availability and protects against data loss. If the ztC Endurance system detects a degradation or failure within the active compute module, Smart Exchange: • Automatically activates the standby compute module and copies over in-process data • Reroutes all I/O and storage connected to the original active compute module to the newly activated compute module Smart Exchange occurs while the system is running and, except for a very brief pause (usually less than one second), is undetectable to the operating system and customer applications.​​ from Standby B to Standby A. See Using Maintenance Mode.

  5. When the Smart Exchange completes, run the following command on Standby A:

    sudo /opt/stratus/sbin/setup_bt install

  6. When the installation completes, return to the ztC Endurance console​ and enable remote support as described in Configuring Remote Support Settings.

Your ztC Endurance system is now ready to use ASNConnect.
